Is it possible the "before" noise was the mounting plate hitting the axle, or was it some other type of noise that was reduced?
If that's the case, I can see where FULL or SHORTENED bump stops would def decrease (darn near eliminate) some noise in your scenario where you had no rubber stops at all.
Interesting how they're called different things on the parts' sites, but the pics confirm same part.
